Variations of the optical observations of time and latitude residuals are derived from two stations, the ILOM arid the USNO. The latitude observation residuals show a correlation with local variations of the horizontal component and the X component of the geomagnetic field. However, time observation residuals show a correlation with local variations of the first time derivative of the geomagnetic field Y component.
Fluid motions in the fluid core are examined by taking into account the temperature gradient in the meridional direction near the CMB. The result shows the possibility of a Rossby type wave to induce variations of the disturbing potential and those of the vertical.
